Abstract (en)

[origin: EP2990676A1] A displacement compensating coupling (1) comprises a first coupling member (4), a second coupling member (5) and connecting elements (6) for connecting the first and second coupling members (4, 5). The coupling members (4, 5) are each made in one piece from composite material and have a first flange portion (4a, 5a) for attachment to one of the drive elements (2, 3), a diaphragm portion (4b, 5b) that extends radially outwardly from the first flange portion (4a, 5a), a second flange portion (4c, 5c) and a tube portion (4d, 5d) extending from an outer circumference of the diaphragm portion (4b, 5b) to the second flange portion (4c, 5c). Each of the tube portions (4d, 5d) has two or more recesses (4f, 5f) that are spaced from each other in circumferential direction by non-recessed portions (4g, 5g). In a first relative position of the first coupling member (4) and the second coupling member (5), representing an assembly mode, the recesses (4f) of the first coupling member (4) face the recesses (5f) of the second coupling member (5) so as to form together apertures for access to an interior (14) of the coupling (1). In a second relative position, representing the operational mode, the recesses (4f, 5f) of the first coupling member (4) and of the second coupling member (5) are offset in circumferential direction and face the non-recessed portions (4g, 5g), respectively. The coupling (1) provides a high compensation potential in relation to its axial length without impairing torque transmission or increasing material usage. It has a high buckling safety and high torsional stiffness.
